How:self:button_number() or self:button_number(number)
number: signed integer
What: This function when given no parameter, returns the # number of the control element. These numbers are from the top left, read left to right, top to bottom 0 to 15 OR in the case of the PBF4 from 0 to 11.
When this function is given a parameter, it will set the # number of the control element to the number given.
How:self:button_value() or self:button_value(value)
value: integer, ranging 0...127
What: This function returns the value associated to the button. By default, this value is 127 when the button is pressed down and 0 when released.
When this function is given a parameter, it will set the value associated with the button state according to the parameter given.
When using other types of button modes, described later in this chapter, the button values are evenly spread across the steps: eg. spilt 3 was would be values 063127 split 4-way would be 04795 and 127.
Example: Inputting the code self:button_value(127) will make all button press and button release event return the value 127.
What: This function returns the minimum value of the "released" button state. This is 0 by default.
When given a parameter, this function changes the minimum value of the button state according to the value given as parameter.
Example: The code self:button_min(20) will set the value of the button to 20 when released.
What: This function returns the maximum value of the "pressed down" button state. This is 127 by default.
When given a parameter, this function changes the maximum value of the button state according to the value given as parameter.
Example: The code self:button_max(110) will set the value of the button to 110 when pressed down. This can be useful to set easy to use values for a switch, like self:button_max(1) will make it so that there are only two values this button can send out 0 and 1.
What: This function returns the value of the button mode. This is 0 by default. Button mode means how many 'steps' the button has between its maximum and minimum value. For example when the function is used to set this value like this: self:button_mode(mode) the resolution parameter will govern the number of steps.
Example: The code self:button_mode(2) will make the button a 3-step switch. The three states will be 0 , 63 and 127.
What: This function will return the "state" of the control element. In case of a button this is either "pressed down" 127 OR "released" 0. These values independent from value variable of the control element. This means that the button_state() function will always return the values associated with the "pressed" or "released" states, independently from any kind of alterations to the button value functions, such as changing the max or min values.
How:self:encoder_number() or self:encoder_number(number)
number: signed integer
What: This function, when given no parameter, returns the # number of the control element. These numbers are from the top left, read left to right, top to bottom 0 to 15.
When this function is given a parameter, it will set the # number of the control element to the number given.
How:self:encoder_value() or self:encoder_value(value)
value: integer, ranging 0...127
What: This function returns the value of the encoder state. By default, this value is 0 when the encoder is turned and tops out at 127.
When this function is given a parameter, it will set the value associated with the encoder state according to the parameter given and will output that value on each trigger.
What: This function returns the minimum value configured to the encoder minimum state. This is 0 by default.
When given a parameter, this function changes the minimum value of the encoder state according to the value given as parameter.
Example: The code self:encoder_min(20) will set the starting value of the encoder to 20 when rotated.
What: This function returns the maximum value configured to the encoder maximum state. This is 127 by default.
When given a parameter, this function changes the maximum value of the encoder state according to the value given as parameter.
Example: The code self:encoder_max(110) will set the end value of the encoder to 110 when turned.
How:self:encoder_mode() or self:encoder_mode(mode)
resolution: integer, ranging 0...2
What: This function returns the value of the encoder mode. This is 0 or "absolute mode" by default.
When function is given 1 as a value, it will change the encoder to "relative mode binary offset". In this mode turning the encoder 'backwards' or counterclockwise will always result in the value 63 and turning it 'forwards' or clockwise will always result in the value 65 .
When the function is given 2 as a value, it will change the encoder to "relative mode 2's comp". In this mode turning the encoder 'backwards' or counterclockwise will always result in the value 127 and turning it 'forwards' or clockwise will always result in the value 1 .
Example: The code self:encoder_mode(1) will change the encoder into relative mode.
How:self:encoder_velocity() or self:encoder_velocity(velocity)
velocity: integer, ranging 0...100
What: This function returns the value of the encoder velocity parameter. This is 100 by default. When the function is given a value for the velocity parameter, it will set the encoder velocity to that value. Velocity increases the steps the encoder value increases on each tick, depending on the speed of rotation. Setting the velocity parameter to 0 turns off encoder velocity completely.
Example: The code self:encoder_velocity(0) will turn off the velocity increase function of the encoder. In this case turning the encoder by one tick, will increase the value of the encoder by 1.
